A hoagie? Sure. PB&J? Absolutely. A burrito? Nope! But why? With a wheat or flour wrapping that usually encases meat and other fixin’s, it seems like it’d qualify just like a pita or anything else normally considered a sandwich.

Well, The Atlantic has put this question to rest with 4 solid qualifications that will help you figure out, what exactly is a sandwich?

I would define a sandwich as this: Any form of fixings with two breadings of any nature that do not touch each other but both support and top the fixings, This would include typical renditions, submarine sandwiches, hoagies, but would not include burritos, piroshki, or any other surrounding “containers” that are not separated into two parts.
